The current season sits quite comfortably in 4 calendar weeks, seasons always start every fourth Sunday - any adjustment risks confusing managers as to when the actual start of the season is. However, I'm not adverse to the idea, as long as the full effect of an inter-season break is simulated, e.g. injuries that are still applicable at the end of the season are 'cured' (or vastly reduced in the case of long-term injuries) before the new season starts.
